1 Claim.

The invention relates to improvements in rubber stamps and has for its object the provision of an improved construction of this character provided with improved means for mounting and retaining the stamping element.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawing forming a part of this specification, and in which Fig. 1 is a side view of a rubber stamp embodying the invention;

Fig. 2 an end view of the same; and

Fig. 3 a perspective view of one end of the stamping element.

The embodiment of the invention illustrated in the drawing comprises a base formed from a. piece of sheet metal bent centrally to form a tubular cylindrical handle member 15, the sides of the sheet being then brought together to form a Web or shank 16, secured together by rivets 17, the ends of the sheet being then separated and bent to form a channel member 18 provided with re-entrant retaining flanges, as best shown in Fig. 2, thereby forming a simple, economical and effective combined handle and supporting element, all from one sheet of metal.

The stamping element consists of a rubber strip or block 12, having the letters 13 formed in relief thereon as indicated. The block 12 is adhesively secured to an enlarged base or cushion 14, of sponge rubber, arranged to fit into an open end of the channel 18 and engage under the reentrant flanges at the edges thereof, thereby securely mounting the stamping element on the combined handle and supporting element.

By this arrangement a rubber stamp is provided having a stamping element removably attached to the supporting head without the use of either glue or metal tacks or nails.

The ink necessarily used in conjunction with the stamping element has a tendency to attack and. destroy the glue and thus separate the stamping element from the supporting head. The glue also has a tendency to harden and solidify the rubber cushion or base, which is objectionable. All these objections are obviated by the above arrangement, which requires neither tacks nor glue to pended claim.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

A rubber stamp comprising a base of sheet metal bent centrally to form a handle, the ends of said strip being brought together and then separated to form a sheet metal channel, the edges of said channel being provided with reentrant flanges and the ends thereof being open for the insertion of a stamping element; and a rubber stamp having an enlarged base fitting into said channel and under said reentrant flanges.

ALEXANDER J. REYNOLDS.
